What Is a DIY Epoxy Tumbler?

A DIY epoxy tumbler is more than just a cup—it’s a creative canvas you can turn into a functional piece of art. At its core, it’s usually a stainless steel tumbler that you decorate with your favorite paints, glitter, vinyl decals, or even hand-painted designs. Once your design is complete, the entire surface gets sealed with a clear coat of epoxy resin, giving it that signature smooth, glossy, and glass-like finish.

What makes a DIY epoxy tumbler so popular? For starters, it’s completely waterproof, scratch-resistant, and made to last. You can personalize it with names, themes, or color blends to match your vibe. Whether you're making one as a heartfelt gift, crafting a whole set for your bridal party, or looking to launch your own tumbler business, these custom cups are the perfect blend of fun, function, and flair.

In short, a DIY epoxy tumbler is where creativity meets durability, and once you make one, you’ll probably want to make more!

Step-by-Step Guide to Making a DIY Epoxy Tumbler

Step 1: Prep Your Tumbler

Start by cleaning your tumbler with rubbing alcohol to remove any residue or oils. Lightly sand the surface for better adhesion if needed. Tape off the rim to avoid epoxy where your lips go.

Pro Tip: Wear gloves and work in a well-ventilated area. Epoxy resin can get messy (and sticky)!

Step 2: Add Base Color or Glitter

Use ColorFix Paints for a solid base coat. Once dry, you can apply glitter using Mod Podge or tacky spray.

Sprinkle your favorite Fill-a-Bag Glitter for sparkle, shine, and depth. Want ombré or custom blends? Mix your own colors for a truly unique look.

Step 3: Mix Your Epoxy

Use a 1:1 ratio to mix Artistry Tumbler Art Epoxy or try the Fast Set Thick Viscosity Formula for faster results. Stir slowly to avoid bubbles, and mix thoroughly for 3–5 minutes.

Expert Tip: If you're short on time, use HyperSpeed Tumbler Glaze for a super quick, high-gloss coat.

Step 4: Apply Epoxy to Tumbler

Place the tumbler on your cup turner. Slowly pour and smooth epoxy over the surface while it spins. Use a heat gun or torch to pop any bubbles after application.

Let the epoxy self-level and cure according to the product instructions.

Step 5: Let It Cure

Curing time varies depending on the epoxy. Standard formulas take about 8–12 hours, while fast-set versions can cure in as little as 2–4 hours.

Mistake to Avoid: Don’t touch your tumbler before it's fully cured. You’ll leave fingerprints or smudges that are hard to fix.

Step 6: Add Final Touches

If you want to add decals or names, apply them after the first epoxy layer cures. Then, seal with another epoxy layer to lock everything in.

Repeat as needed for multiple layers or effects (like mica powders or inks).

Common Mistakes to Avoid

• Not mixing epoxy properly: Incomplete mixing leads to tacky or soft finishes.
  

• Pouring too thick: Causes uneven curing or sagging.
  

• Skipping surface prep: Oils and residue can ruin adhesion.
  

• Ignoring cure time: Rushing can cause dents or fingerprints.

Expert Tips for Stunning Tumblers

• Use a digital scale for perfect epoxy measurements.
  

• Always warm up your epoxy slightly to reduce bubbles.
  

• Add layers of glitter between epoxy coats for extra dimension.
  

• Store tumblers in a dust-free space during curing.
